[Blaze] can be used instead of [Scattering Inferno] for more damage overall, at the cost of some status chance. While the damage increase is nice, this is a status weapon that'll gain more DoT (Damage over Time) with more status chance, since you'll get Viral procs, Heat procs, and Slash procs from [Hunter Munitions], and the weapon's innate slash damage.
If you don't want to use [Hunter Munitions] for any reason, you can use [Sweeping Serration]. This will increase the weapon's innate slash damage, and increase the amount of Slash procs on the target. With this mod, the priority of elements will be Viral > Slash > Heat > Radiation (current build has Heat > Slash, but excludes Hunter Munition procs).
I prefer the [Sweeping Serration] build, to be honest, but I'm aware everyone likes [Hunter Munitions].
You can go with a Magnetic [Kuva Drakgoon] instead of Radiation. Magnetic is great versus shields, and Nullifiers; Radiation is a great crowd control, and disables Ancients.
